Hi,
I'm using Inspire to design a support for a satellite for a project for the university and since the weight has to be as low as possible once i designed the structure I ran a reticular optimization and got my piece. The analysis that is automatically run with this kind of optimization gave me the safety factor and dispacement info that i needed but i would need to run also an analysys to know the first normal frequency of oscillation of the structure but once i try to launch the pre optimization part substitues the reticular part. How can i do? 
to be more clear. This is the reticlar part of which i should analize the frequency

and this is the part that lets me analyze.
Is there any way to eliminate the pre optimization part?
Also i would need to analyze the inclination of the reticular piece under thermal loads but i don't know exactly how.
Thank you in advance
